In
the past 24-hour period, the TVN recorded fourteen (14) volcanic earthquakes,
including ten (10) volcanic tremor events having durations of two (2) to three
(3) minutes, and four (4) low-frequency volcanic earthquakes. Activity at
the Main Crater was dominated by upwelling of hot volcanic fluids in its lake
which generated plumes 1,000 meters tall that drifted southwest. Sulfur dioxide
(SO2) emission
averaged 6,957 tonnes/day on 25 March 2022. Temperature highs of 63.7°C were
last measured from the Main Crater Lake on 25 February 2022. Based on ground
deformation parameters from electronic tilt, continuous GPS, and InSAR
monitoring, Taal Volcano Island and the Taal region has begun deflating in
October 2021.
After
the phreatomagmatic eruption of the Main Crater at 07:22 AM to 08:59 AM
yesterday (26 March 2022), two (2) subsequent phreatomagmatic events at 4:34 AM
and 5:04 AM today have been recorded by the Taal Volcano Network or TVN based
on seismic records and visual cameras. These events produced 800 meter- and
400-meter-tall plumes, respectively, from the Main Crater that drifted
southwest.

The Alert Level 3 (Magmatic Unrest)
prevails over Taal Volcano. This means that there is a magmatic intrusion at
the Main Crater that may further drive succeeding eruptions. DOST-PHIVOLCS
strongly recommends Taal Volcano Island and high-risk barangays of Bilibinwang
and Banyaga, Agoncillo and Boso-boso, Gulod and eastern Bugaan East, Laurel,
Batangas Province be evacuated due to the possible hazards of pyroclastic
density currents and volcanic tsunami should stronger eruptions subsequently
occur. The public is reminded that the entire Taal Volcano Island is a Permanent Danger
Zone (PDZ), and entry into the island as well as high-risk
barangays of Agoncillo and Laurel must be prohibited. All activities on Taal
Lake should not be allowed at this time. Communities around the Taal Lake
shores are advised to remain vigilant, take precautionary measures against
possible airborne ash and vog and calmly prepare for possible evacuation should
unrest intensify. Civil aviation authorities must advise pilots to avoid flying
over Taal Volcano Island as airborne ash and ballistic fragments from sudden
explosions and pyroclastic density currents such as base surges may pose hazards
to aircraft. DOST-PHIVOLCS maintains its close monitoring of Taal Volcano and
any new development will be communicated to all concerned stakeholders.
